Use the fact that the length of an arc intercepted by an angle is proportional to the radius to find the area of the sector given r = 2 cm and Θ = π/3.

A)3π/4 cm2

B)2/3π cm2

C)3π/2 cm2

D)4π/3 cm2

Areasector  =  (1/2) radius^2  * ( theta in radians)

 

So

 

(1/2) (2)^2 ( pi/3)  =

 

(2/3) pi   cm^2
